SPECIFICATION forming part of Letters Patent No. 734,084, dated July 21, 1903.

Application filed November 10, 1902. Serial No. 130,789. (No model.)

To all whom it may concern:

Be it known that I, CLAUDE JOSEPH OLLAG- NIER, a citizen of the Republic of France, re-

siding at l Rue Lentonnet',Paris,France, have invented new and useful Improvements inAutomotor-Carriages, of whichthe following is a specification.

This invention consists in the application to automotor-carriages of, first, differential hicle; Fig. 3, a back view thereof; Fig. 4, a

plan. Fig. 5 represents the Cardan or suspended shaft. Fig. 6 is an elevation of the device for working the steering-wheels, and Fig. 7 a plan of Fig. 6.

This vehicle is distinguished by a special means for constituting all the four wheels driving-wheels, the two front wheels being for the object of increasing the cohesion, getting over obstacles, and insuring normal action, whatever the state of the roads, in connection with vehicles especially intended for the conveyance of heavy loads.

The superheated steam is conveyed from the generator 'It into the engine, Figs. 2 and 4, placed in the front under the framer. The shaft of the engine (not shown in the drawings) carries wheels which engage with the speed-change wheels o w, mounted to slide on the shaft 00, on whose end a pinion y is mounted and actuates the differential gear 2, by means of which motion is imparted, on the one hand, to the wheel a, actuating the differential gear 1) for Working the front wheels 0' d, and, on the other hand, the tooth-rim e and the chain f" of the difierential gear 9, intended for the back Wheels. The back wheels m aredriven through the tooth-wheels t", keyed to each end of the differential-gear shaft g, and the chains is, which drive the tooth-wheels Z', 1nounted on the hubs of the wheels. The band-brake c is wound on the ports 0' and the movable supports 19, bolted to the flats .of the pivoted axle q. The two ends of this axle receive toothed wheels 1, with which the vertical chains .9" are geared, and transmit motion to the toothed wheels t, keyed to the hubs of the front wheels 0' d, which they actuate and which become driving-wheels.

Fig. at shows the position of the divided shaft with flexible joints, the vehicle running straight. v

The steering is effected with the vertical hand-wheel 10, connected by upper pinions with the flexibly-jointed steering-rod o, Figs. 3 and 6, which rises and falls according to the oscillations of the frame in the slide of the socket to. At the end of this socket are lower gearings w for actuating the endless screw y and the tooth-sector z',with which it engages. This sector is mounted in the flat of the right-hand axle, conveys rotary motion to the pivot-axis of the axle, and transmits it to the other wheel by means of the steeringrods a.

Fig. 5 shows the position of the divided shaft and of the flexible joints n, the wheels turning to their greatest possible extent. The articulations thus produced,nevertheless,are limited in consequence of the slides 12'.

The movable supports 10' being fixed on the flats of the axles are actuated in the same direction as the wheels. The vertical chains do not undergo any alteration in form. They act constantly on the wheels always rendered driving and steering wheels, whatever their position may be.

Figs. 6 and 7 explain the motion of the driving-wheels.

IOC

The coke-box e is near the generator. It is closed in front by doors, leaving free access to the boiler. The back of this box or compartmentis movable in the upper part, which when the loading is beingeffected assumes the position of an inclined plane.

The sand-compartments d are arranged on each side of the coke-compartment. They are utilized by means of the pipe-chutes f.

g h" are feed-reservoirs, 1' the platform, and 7c the coal-trucks.

The Windlass land finally the coupling m", furnished with its spring a", are attached in the direction of the longitudinal parts of the frame, so as to be employed for trailing vehicles.

I claim 1. In combination in a motor road-vehicle the front wheels, each of which is independently pivoted to be adjusted about a vertical axis, a divided flexible shaft, a differential gear for driving the said divided shaft, driving means between the divided shaft and the hubs of the front wheels and extending vertically at each end of the divided shaft, the said divided shaft being supported over the axles of the front wheels to be adjusted therewith and means foradj usting the front wheels, substantially as described.

2. In combination in a motor road-vehicle,

the front wheels having their axles pivotally supported, a divided flexible shaft, a differential gear for driving the said shaft, said divided shaft being arranged in a plane above the plane of'the axles of the wheels, a drivechain connection between the ends of the divided shafts and the Wheel-hubs, means for adjusting the wheel-axles about their pivots and a support for the outer ends of the divided shaft extending from the journals of the pivoted axles, substantially as described.

3. In combination, a divided shaft, a dinerential gear at the center of the said shaft,fixed supports for the central portion of the said divided shaft, flexible joints n in said shaft, movable supports 19 for the ends of the flexible shaft, the wheels 0 d, the pivoted axles q for the said wheels carrying the said movable supports p', the chain-wheels n on the hubs of the wheels 0 d and upon the ends of the flexible shaft and the chain connection between the said chain-wheels at each end of the shaft, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of October, 1902.

CLAUDE JOSEPH OLLAGNIER.
